Answer:
x >>>>>>>> f(x)
–9 >>>>>> 10
–7 >>>>>>> 0
0 >>>>>>>> –35
5 >>>>>>>> –60
Step-by-step explanation:
f(x) = –5(x + 7)
1. x = –9, f(x) =?
f(x) = –5(x + 7)
f(x) = –5(–9 + 7)
f(x) = –5(–2)
f(x) = 10
2. f(x) = 0, x =?
f(x) = –5(x + 7)
0 = –5(x + 7)
Divide both side by –5
0 / –5 = x + 7
0 = x + 7
Collect like terms
x = 0 – 7
x = –7
3. x = 0, f(x) =?
f(x) = –5(0 + 7)
f(x) = –5(7)
f(x) = –35
4. f(x) = –60, x =?
f(x) = –5(x + 7)
–60 = –5(x + 7)
Divide both side by –5
–60 / –5 = x + 7
12 = x + 7
Collect like terms
x = 12 – 7
x = 5
SUMMARY:
x >>>>>>>> f(x)
–9 >>>>>> 10
–7 >>>>>>> 0
0 >>>>>>>> –35
5 >>>>>>>> –60
Answer:
They are not parallel because their slopes are not equal
Step-by-step explanation:
It will take Mr. Jenkins 1 hr and 20 minutes to cut all the grass.
To know how long it will take Mr. Jenkins to cut all the grass, get the total area of the lawn and divide it by the rate Mr. Jenkins cut the grass.
The area of the lawn can be calculated using the formula for the area of a rectangle given by:
A = l x w
where l is the length and w is the width.
Using this formula, the grass lawn that is 24 m wide and 30 m long has an area of:
A = l x w
where
l = 30 m
w = 24 m
A = 30 m x 24 m
A = 720 m^2
Meanwhile, the time it will take Mr. Jenkins to cut the grass lawn with an area of 720 m^2 can be computed using the rate.
amount = rate x time
720 m^2 = 9 m^2/minute x t
t = 720 / 9
t = 80 minutes = 1 hr 20 minutes

Hello!
If he has 15 and gives away 3 he has 12. If he gives away 5 more he will have 7.
I hope this helps!
